在文件中搜索并替换为，空格数量未知

我正在寻找有关搜索和替换文件中的字符串的小帮助。

我的文件内容

hostssl  all       all  192.168.10.1/16                    pam pamservice=postgresql clientcert=    1
hostssl  all       all  192.168.10.2/16                    pam pamservice=postgresql clientcert=1
hostssl  all       all  192.168.10.3/16                    pam pamservice=postgresql clientcert=   1
hostssl  all       all  192.168.10.4/16                    pam pamservice=postgresql clientcert=  1
hostssl  all       all  192.168.20.1/16                    pam pamservice=postgresql clientcert=1
hostssl  all       all  192.168.20.2/16                    pam pamservice=postgresql clientcert=1
hostssl  all       all  192.168.20.3/16                    pam pamservice=postgresql clientcert=1
hostssl  all       all  192.168.10.5/16                    pam pamservice=postgresql clientcert=1
hostssl  all       all  192.168.10.6/16                     pam pamservice=postgresql clientcert=1
hostssl  all       all  192.168.10.7/16                    pam pamservice=postgresql clientcert=      1

我尝试使用以下命令

sed -i "s/clientcert=*1/clientcert=verify-full/g" pg_hba.conf

它的作用不是预期的结果

hostssl  all       all  192.168.10.1/16                    pam pamservice=postgresql **clientcert=    1**
hostssl  all       all  192.168.10.2/16                    pam pamservice=postgresql clientcert=verify-full
hostssl  all       all  192.168.10.3/16                    pam pamservice=postgresql **clientcert=   1**
hostssl  all       all  192.168.10.4/16                    pam pamservice=postgresql **clientcert=  1**
hostssl  all       all  192.168.20.1/16                    pam pamservice=postgresql clientcert=verify-full
hostssl  all       all  192.168.20.2/16                    pam pamservice=postgresql clientcert=verify-full
hostssl  all       all  192.168.20.3/16                    pam pamservice=postgresql clientcert=verify-full
hostssl  all       all  192.168.10.5/16                    pam pamservice=postgresql clientcert=verify-full
hostssl  all       all  192.168.10.6/16                     pam pamservice=postgresql clientcert=verify-full
hostssl  all       all  192.168.10.7/16                    pam pamservice=postgresql clientcert=      1

请让我知道通过忽略“=”和1”之间的空格将“clientcert= 1”替换为“clientcert=verify-full”的最佳替代方法

我找到了答案。下面的代码对我有用

sed -i "s/clientcert=[[:space:]]*1/clientcert=verify-full/g" pg_hba.conf
